whisper: wearable body architectures was the first in a series of three interactive wearable public art installations that explore interaction with one징짱s own body data. whisper is an acronym for [wearable, handheld, intimate, sensory, personal, expressive, responsive system], a term that is now used to describe the focus of the research group. The whisper installation is based on small wearable microcontrollers, and wireless network transmission using physiological data: heart rate and breath. Sensors are embedded in a soft white jacket-like garment with detachable sleeves, reminiscent of a hybrid kimono, pajama and smoking jacket constructed in a soft comforting fabric. Visualization and sonification of body data interaction is projected onto the floor in small 징째light pools징짹. Participants can share data through specially designed snaps located on the jackets. Connection snaps are positioned to create playful and intimate movement interaction. Multiple participants can 징째snap together징짹 to create group data-bodies and to engage with their output through their movement.
